Application filed May 11, 1908. Serial No. $32,095.

1'0 all whom it may concern:

Be it known that 1, Bauer M. W. HAN- soN, a citizen of the United btates, residing at liarttord, in the county of Hartford and btate of Connecticut, have invented certain new and useful Improvements in Bearing-Guards, of which the following is a specification.

This invention relates to bearing-guards,

the object of the invention being to provide a device of this character which is simple in construction and which etl'ectually protects bearings from the deleterious action of foreign substances of various kinds.

The device can be employed with advantage in many difi'erent connections although it is of particular utility when used in conjunction with the slide and bed or equivalent parts of a metal-working machine.

In the drawings accompanying and forming part of this specification I have represented in detail one form of embodiment of the invention which to enable those skilled in the art to pratice the same will. be set forth at length in the following description while the novelty of the invention will be included in the claims succeeding said description. In said drawings I have represented a bed and slide of a metal-working machine which may be such a one as is utilized for reducing the diameter of metal stock. 7

Referring to said. drawings, Figure 1 is a sectional end elevation of the bed and slide of a metal-working machine, and Fig. 2 is a detail view 'in section of one of the sections of said slide.

Like characters refer to like parts in both figures of the drawings.

In Fig. 1 I have shown the bed of a machine of the class to which allusion hasbeen made, the same being denoted by 2 and having two bearii'igs or ways as 3 and l for a slide sum as that denoted in a general way The hearing or way 3 is of substantially channel form being shown as of V- shape to receive the correspondiugly-formed tongue 6 depending from said slide. The hearing at is hori /ioutal or flat and it susi tains for traveling movement a like surface 1 vandan auxiliary section as 8.

i on the underside of the slide 5, the latter in the present instance reciprocating upon .two bearings or ways laterally separated :from

.each other.

The slide 5 is shown as being of compound construction, comprising a main section as 7 I employ these terms simply for convenience of description as the auxiliary section 8 except as to size is in no sense subordinate to the main section. There are advanta es follow ing the sectional organization 0? the slide 5 as will hereinafter be made apparent. The two sections of the slide may be rigidly united together in any desirable manner for example by means of a screw or screws as 9, the fastening means in question connecting the auxiliary section 8 with-the main section 7 on theunder'side of the latter.

A rack-bar 10 is shown as rigid with the auxiliary section '8, the .teeth of said rackbar meshing with a pinion as 11 'rotatively.

supported upon the bed 2 and :by turning which the slide 5 can be moved back :an forth uponsaid bed 2,. the means mentioned being a familiar one for operating slides. It might be stated that the V-shaped art to which reference has been made is ormed upon said auxiliary section 8 while the bearing face which travels upon the bearing area l is formed upon the main section 7. The two sections 7 and 8 of.thc slideare separated so as to produce a channel 12 one wall of which is on one of said sections .while the other wall of which is on the other of said sections and this channel receives a portion of a guarcbplate as 13 which serves in part as a protecting means for the bearing 3. The substantially upright or vertical hotly of said guard-plate 13 is represented as fastened to the bed 2 and for this purpose a screw or screws as 14 may be provided. The guard-plate 13 is furnished with an angular flange as 15 which extends into the similarly disposed channel 12the free end of said flange having a downtnrned'lip or head as 16 contiguous to the bottom of the channel near the inner end thereof. Said ardplate covers a rel-at ively-considerable area and prevents the passage of flying particles a discharge duct as 21 leads.

"screws, to the auxiliary section 8 thereof;

This guard-member 17 is provided with a vertical flange as 18 and a crown or head flange as 19, the two flanges merging into each other to provide in effect a continuous flange and the flange 19 beingangularly disposed and overhanging the inner portion of the flange 15. Should anyforeign matter be directed against the flange 18 it will pass down the outside of the same without getting at the bearing 3 while should any of such matter fall upon the inclined flange 19 it Will pass from the latter onto the inclined flange 15 and travel down the latter to the body of the guard-plate 13 which will dispose of it without possibility of its entrance to the bearingB. The bearing 3 is therefore thoroughly protected. It is conceivable that clear water or oil might pass between the lip or bead 16 and the bottom of the channel 12 and I provide a means whereby such water or other liquid cannot obtain access to the bearing 3.

In the upper side of the auxiliary section 8 I have shown-a trough or gutter as 20 closed at its opposite ends and from the said trough or gutter between its .top and bottom Said duct may consist of a tube somewhat bent and assin throu h a 1'0 erl -formed 0 )eninm p D b b in said section 8. Should any liquid pass under the lip 16 it will flow down the inclined upper side of the auxiliary section 8 which upper side is the bottom of the channel and from thence into the trough or gutter 20, escaping from the latter into the duct 21 which leads such liquid away from the hearing 3. It is therefore impossible for either liquid or solid matter to reach said bearing 3. The bearin 4 is also adequately protected and for thi purpo'se a pair of guard members may be effectively utilized,- one of said guard members consisting in the present case of a plate as 22 which is rigidly fastened in some suitable way to the bed 2 andwhich is represented as standing at an inclination so as to protect one side of the bearing 4. The other guard member of said latter pair denoted by 23 and it is' fasten d in some convenient way to the slide 5. The guard-member 25 has two side flanges as 24 and 25 disposed practically at right angles to each other and both inclined to the horizontal. The flange 25 overlaps the guard-plate 22 and with the latter prevents matters and can run smoothly with the least amount of friction.

lVhat I claim is: 1. A slide in sections connected together to present a channel, the walls of which are respectively on said sections, said slide having a trough in communicationwith said channel.

2., A slide in sections connected together to present a channel, the walls of which are respectively on said sections, said slide having a trough below and in communication with the channel, the ends of the trough being closed and the slide having a discharge duct leading from said trough.

3. The combination of a bed and a. slide, the former having a bearing for the latter and the slide being formed in sections connected together to presenta channel, and a. guard-plate for said bearing, fastened to said bed and extending into said channel.

4. The combination of a bed and a slide,'

the former having a bearing for the latter, the slide having a channel and a trough below the channel, the channel being inclined, a guard plate fastened to the bed and provided with a portion extending into the channel and across the trough, and a guardmember fastened to the slide and having a portion overlapping the first mentioned por 5. The combination of a bed and a slide, the former having a bearing for the'latter, the slide-having an inclined channeland a trough below the channel, a guard-plate fastened to the bed and having an inclined flange extending into said channel and contiguous to the bottom thereof the flange crossing said trough, and a guard-member fastened to the bed having a vertical flange and a crown-flange the latter being at an inclination and overlapping the other flange.

6. The combination of a bed, a slide supported on said bed and having a channel provided with a trough, and a 'guard fas tened-to said bed, extending into said chan-' nel and entirely across the trough the inner terminal of said guard being contiguous to wall, and a discharge duct leading from said 10 one wall of said'channel. trough.

7. The combination of a bed, a slide sup- In testimony whereof I affix my signature ported by said bed and having a channel in presence of two witnesses.

provided on the lower wall thereof with a t trough having closed ends, a guard fastened BENGT HANSON to said bed, extending into the channel and Witnesses:
